Police already arrested 24-year-old Calvin Young of Cleveland for tampering with evidence and abuse of a corpse, the station reports. The Cuyahoga County Medical Examiner's Office says Johnson died of a gunshot wound to the head and stab wounds to her torso, arms and legs. Johnson's body was discovered on March 22 outside a vacant home in Cleveland Heights, a month after she was reported missing. Investigators believe she was killed around February 26, according to WOIO.

In a statement to the press last week, Miriam's brother Nathan Johnson said his family is grateful to those who have been investigating her murder.

"While we hope that the criminal case continues to progress, we hope that Miriam can be honored by an increase in love and compassion, and an increased awareness of those who are threatened by violence, and entrapped in abusive relationships," Johnson said.

Johnson said his sister's children are safe in the care of people who love them.
